The members of Led Zeppelin have had other business in New York this week, besides holding a press conference and attending the premiere of their new concert film, Celebration Day. They've been spending time with CBS correspondent Anthony Mason for a piece on CBS Sunday Morning that will air between Thanksgiving and Christmas.

On Monday, Mason and Robert Plant walked down St. Mark's Place in New York's East Village neighborhood, the site of the two apartment buildings that make up the cover of Zeppelin's 1975 album Physical Graffiti. Of course, a few tourists began snapping away when they were surprised to see Plant.

The two buildings are also featured in The Rolling Stones' video for "Waiting on a Friend." There's a tea shop called Physical Graffitea in the basement of one of the buildings, at 96 St. Mark's Place.
